Swiss Bitcoin Pay primary sources — 2026-05-02

Project status in this pass

  • No canonical standalone whitepaper or litepaper surfaced.
  • The clearest current source of truth is Swiss Bitcoin Pay’s merchant API docs plus the project’s own open-source application and plugin repositories.
  • The materials consistently make Swiss Bitcoin Pay look broader than a simple POS app or wallet.

Primary-source snapshots

1) Merchant app repository

  • URL: https://raw.githubusercontent.com/SwissBitcoinPay/app/main/README.md
  • Key excerpt:
    • The README describes Swiss Bitcoin Pay as an easy-to-use solution to accept bitcoin payments in business.
    • It says the app is available across web, iOS, and Android, requires no KYC identification, is non-custodial through free daily auto-withdrawal to the merchant’s own wallet, supports total or partial auto fiat conversion, works worldwide with most currencies, and supports multiple employees.
    • This is strong evidence that the project is packaging merchant operations rather than only a consumer wallet.

2) Merchant API docs

  • URL: https://docs.swiss-bitcoin-pay.ch/
  • Key excerpt:
    • The API reference exposes a detailed invoice object with status fields, payment details arrays, Lightning payment requests, fiat and bitcoin amount fields, redirect behavior, device metadata, and onchain transaction-confirmation fields.
    • The response shape suggests Swiss Bitcoin Pay models merchant checkout and settlement flows directly, not merely simple address display.
    • The coexistence of Lightning and onchain fields is a useful clue that the product handles multi-rail merchant acceptance.

3) WooCommerce plugin

  • URL: https://raw.githubusercontent.com/SwissBitcoinPay/woocommerce-plugin/main/README.md
  • Key excerpt:
    • The plugin README says merchants can accept both onchain and Lightning payments in WooCommerce via Swiss Bitcoin Pay.
    • Setup requires an API key and an API secret (HMAC) from the Swiss Bitcoin Pay dashboard.
    • That is clear evidence of production ecommerce integration support and authenticated merchant API access.

4) BoltCard Terminal Tools app

  • URL: https://raw.githubusercontent.com/SwissBitcoinPay/boltcard-tools-terminal/main/README.md
  • Key excerpt:
    • The README says the app lets a user scan a merchant invoice with a phone, tap a Bolt Card on the phone, and pay the merchant directly peer-to-peer from node to node.
    • It also says users can pay onchain invoices with the Bolt Card by using Swiss Bitcoin Pay’s integrated swap service.
    • This extends Swiss Bitcoin Pay beyond a standard cashier app into card-assisted merchant-payment tooling.

5) Official site

  • URL: https://swiss-bitcoin-pay.ch/
  • Key excerpt:
    • The official site title frames the project around accepting Bitcoin in business.
    • Search results for the site also surface a Lightning-native card alongside merchant acceptance messaging.
    • Even with sparse recoverable page text in this pass, the site still aligns with the merchant-control-plane reading supported by the repos and API docs.

Working conclusion

Swiss Bitcoin Pay is best cataloged as a non-custodial Bitcoin merchant-acceptance control plane with Lightning, onchain, ecommerce, and Bolt Card-adjacent tooling. The decisive evidence in this pass was the combination of cross-platform merchant apps, auto-withdrawal to merchant-controlled wallets, optional fiat conversion, multi-employee support, an authenticated merchant API, a WooCommerce plugin, and a separate Bolt Card payment utility with integrated swap support.
